Attempting to recovery failed XA transactions from a datasource using:

<security-domain>DefaultDSRealm</security-domain>

Where the security realm's login module implementation is org.jboss.resource.security.JaasSecurityDomainIdentityLoginModule. For example:

<application-policy name = "DefaultDSRealm">
<authentication>
<login-module code = "org.jboss.resource.security.JaasSecurityDomainIdentityLoginModule"
flag = "required">
<module-option name = "username">user</module-option>
<module-option name = "password">oLxZUT0uKnAfS.zbvaEZd</module-option>
<module-option name = "managedConnectionFactoryName">jboss.jca:service=XATxCM,name=XAOracleDS</module-option>
<module-option name = "jaasSecurityDomain">jboss.security:service=JaasSecurityDomain,domain=ServerMasterPassword</module-option>
</login-module>
</authentication>
</application-policy>
